The n inie il designates a pump cylinf :hambm, whereby the air will become laden with the powdered insecticide which then is discharged through the rear opening 35.

Screw-threaded upon the rear end of the tubular beam 5 is a coupling 40, having con nection with a flexible hose 41, equipped at their outer ends with separate nozzles 42. 'l. he hose 411 diverge rearwardly and extend beyond the outer sides of the handles 11 and may be supported at selected elevations by means of strap irons 43, which are vertically adjustably attached to the handles 13, as shown.

In view of the foregoing description it will be seen that I have provided a dusting machine, so constructed that all parts there of are balanced. By virtue of the location of the pumping cylinder 17, with respect to the traction wheel 8, the usual intermediate gearing is dispensed with, and the force .is applied to the plunger rod 21, from the opposite sides of the traction wheel 8, in a balanced manner. The invention is in no way restricted to the precise type of hopper and mixing chamber, as shown, other suitable forms of hopper and means to mix the powdered insecticide with the air may be employed, although the present illustration has been found to be satisfactory.

A machine of this character is adapted to be driven down the field, between the rows of cotton, and the nozzles 4-2 are adapted to spray the powdered insecticide upon the sides of the adjacent rows of cotton or other plant.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of my invention or the scope of the subjoined claims.

Having thus described my invention, I

, claim 1. In a machine for spraying cotton plants or the like, a longitudinal beam, a traction wheel supporting the forward end of the beam, a pump cylinder extending longitudinally of the beam in balanced relation thereto, a plunger reciprocating within the pump cylinder, a plunger rod connected with the plunger, cranks arranged upon opposite sides of the traction wheel and driven thereby, pitmen connecting the cranks with the plunger rod so that the force from the opposite sides of the traction wheel is ap plied to the plunger rod in a balanced manner, a hopper mounted upon the beam in a balanced manner, means for conducting the air pressure from the pump cylinder to the hopper, and a pair of outlet pipes connected with the hopper and extending laterally therefrom to carry the powdered insecticide to the rows of the plants.

2. In a machine for spraying cotton plants or the like, a longitudinal beam, :1 traction wheel supporting the forward end of the beam, handles attached to the rear portion of the beam, a pump cylinder arranged beneath and secured to the beam and extending longitudnally thereof in balanced relation thereto, a plunger within the cylinder, a pair of cranks arranged upon opposite sides of the traction wheel and driven thereby, pitmen connected with the cranks and with the plunger rod so that the force from the opposite sides of the traction wheel is applied in a balanced manner to the piston rod, a hopper mounted upon the rear end of the beam in a balanced manner, pipe means between the cylinder and hopper, and outlet pipe means connected with the hopper.

3; In a machine for spraying cotton plants or the like, a traction wheel, a beam having its forward portion arranged above and mounted upon the traction wheel in a balanced manner, handles carried by the rear end of the beam, a pump cylinder mounted upon the beam and extending longitudinally of the same in balanced relation thereto, a plunger within the cylinder, a plunger rod connected with the plunger, pitmen connected with the plunger, cranks arranged upon opposite sides of the traction wheel and driven thereby and connected with the pitmen, and spraying means mounted upon the beam and having means nf communication with the cylinder.

4. In a machine for spraying cotton plants or the like, a generally horizontal beam, a traction wheel supporting the forward end of the beam, a cylinder suspended from the beam in a balanced manner, a rod connected with the plunger, a crank driven by the traction wheel, a pitman connecting the crank and rod, spraying means mounted upon the beam, and means of communication between the spraying means and the cylinder.

5. A machine for spraying cotton plants or the like, comprising a tubular beam, a traction wheel supporting the'forward end of the beam, a cylinder suspended from the beam and having communication with the interior of the tubular beam, a plunger within the cylinder, drivng connecting means between the plunger and the traction wheel, a hopper mounted upon the tubular beam and having communication with the interior of the tubular beam, and operating means connected with the outlet of the hopper.

6. In a machine for spraying cotton plants or the like, comprising a tubular beam, a traction wheel supporting the beam, manually operated guide means connected with the tubular beam, a cylinder carried by the tubular beam and havin outlet means in communication with the interior of the tubular beam, a plunger in the cylinder, driving means between the plunger and traction wheel, and a spray means having means of communication with the interior of the tubular beam.

7. In a machine for spraying cotton plants or the like, a tubular beam, a traction wheel supporting the portion thereof, manually operated guide means connected with the tubular beam, air compressing mechanism carried by the tubular beam and in communication with the interior thereof, driving means between the traction wheel and air compressing mechanism, and spray means supported by the tubular beam and in communication with the interior thereof.

8. A machine for spraying cotton plants or the like, a tubular beam provided near its rear end with spaced openings with a partition arranged between said openings, a hopper having a mixing chamber through which the tubular beam passes, said openings being in communication with the mixing chamber, spray means connected with the rear end of the tubular beam, a traction wheel supporting the forward end of the tubular beam, air compressing mechanism mounted upon the tubular beam and driven by the traction wheel, and means of communication between the air compressing mechanism and the interior of the tubular beam upon the forward side of said partition.

In testimony whereof I afiix my signature.
